Made some new 12's today I'm very happy with, but they have FS of 55hz. They sound quite good in a large, somewhat low tuned box, but thinking of SPL box application I see high impedence being an issue though I think there must be some opportunity for efficiency here somewhere.

Interesting. Yeah, Qes/Qts should be insanely low, all things being equal. Seems like either you could fit more layers in the gap or the motor needs a chargin'.

Or maybe that's jes how it is, lol.

Gap is tighter than a 12 year old's shoelaces and if you ever tried to remove something ferrous that was stuck to these motors you wouldn't question the integrity of the neo....really even assuming the neo lost 80% of it's strength it would still have as much magnetic force as the ceramic sig.

Just how it is I think, these motors give some wild specs with aluminum coils as well.

Well, either way, keep doin' it. And I hope you didn't take my suggestions as me underestimating your abilities, wasn't aiming at that.

What you need to do is get some aeros and do some testing.

I didn't get that impression, just saying the neo isn't "worn out". Nor do I really believe that that is an issue to worry about whatsoever.

Super busy getting ready to take a week's vacation. Will have pics next week assuming they survive that long.

97 Jeep Grand Cherokee. I drive over 40K miles a year so I mostly need music, but when I compete everything is sealed at the dash.
